Patent DE-3335387-A1 (DE)
Inventor: MUELLER-SCHLOER CHRISTIAN DR I
IPC: G06F12/14
Filed: 1983-09-29
Abstract: This method is intended to provide a facility for ensuring that a program can only be executed on a permitted target computer. For this purpose, individual instructions in the program are replaced by incorrect instructions and a first table records the instructions that have been replaced and what the correct instructions are. The modified program is compressed to a first checksum by means of a first code and then the first table is combined with this first checksum, using a reversible cryptographically secure transformation function, to give a second table. The DES method is used for the transformation function. The target computer, to which the modified program and the second table are sent, compresses the modified program by means of a second code to a second checksum and combines the second checksum with the second table using the transformation function. Only if the first code and the second code are identical will the result of the combining operation in the target computer produce the first table again, by means of which the original program can be restored from the modified program. To compress the modified program or encode the tables, a coding chip can be used in which the code at the target computer is contained in such a way that it can neither be read nor modified from outside. Finally, the chip can be connected to the target computer in such a way that any separation is immediately detectable. <IMAGE>

Title: Planetary driven welding-wire feed device with elastic pressure-force transmission
Inventor: PAPIC BRANKO
IPC: B23K9/133
Filed: 1983-12-13
Abstract: The planetary driven welding-wire feed device with elastic pressure-force transmission is used in the MIG/MAG welding technique for the simultaneous welding-wire feed. It consists of a body (1) onto which a clamping device (2), which transmits the force via a disc spring (3) and a ring (4) to a jaw pair (5), is screwed and to the opposite side of which body drive wheels (6) are attached. The distance and the pressure force between the drive wheels (6) is set by tightening or unscrewing the clamping device (2). As a result of the inserted disc springs (3), the planetary drive mechanism functions elastically, and any overloading of the construction during the setting is thereby prevented. <IMAGE>

Title: Communications cable unwanted harmonics suppressing circuit - connects active inductors into outgoing cable wires and driving with output of compensating amplifier
Inventor: BAUM WALTER DIPL PHYS
IPC: H04B3/28
Filed: 1983-12-24
Abstract: The circuit suppresses harmonics in communications cables with active reduction protection. The harmonics originate from high-current circuits. The unwanted voltage induced by the high-current circuit in a pilot wire earthed at the remote end is amplified and applied to the primary of a trnasformer whose secondary forms the entire wire of the cable or a section of the sheath. Active symmetric inductos are connected into the cable wires. After the induced unwanted voltage is fed back to the pairs of the cable, harmonic assymetry is detected and fed as compensation to the input of differential amplifier whose output is connected to one turn of the inductor. ADVANTAGE - Improved active reduction protection and suppressed harmonics.

Title: Apparatus for the continuous casting of metals, especially steel, in a curved path, using a dummy bar
Inventor: COLOMBO PIERO
IPC: B22D11/08
Filed: 1984-02-29
Abstract: In this apparatus for the continuous casting of metals, including steel, in a curved path, moving guide means are situated in a region below the casting mould and can be moved in such a way that, during the casting operation, they occupy a rest position at a distance from the path of the cast bar, in which they cannot be reached by any splashes of molten metal in the event of the cast skin breaking. During the introduction of the dummy bar into the casting mould and during the withdrawal of the dummy bar, on the other hand, the moving guide means are moved into their operative position, in which they interact with the outer and/or inner sides of the dummy bar. In order to reduce the length of the dummy bar and hence the length of the continuous casting apparatus, at least one of the moving guide means which acts on the outer side and/or the inner side of the dummy bar in the operative position, is a reversibly driven roller (12), optionally toothed, which is arranged approximately halfway between the casting mould (1) and the withdrawal mechanism (2). The driven roller can be decoupled from its drive and can then also be used as an idling guide roller for the cast metal bar. <IMAGE>

Patent DE-3408635-A1 (DE)
Inventor: CLEMENT ALBRECHT DIPL ING
IPC: F02D41/14
Filed: 1984-03-09
Abstract: The invention is directed to a mixture metering arrangement for an internal combustion engine and includes an exhaust-gas sensor which is exposed to the exhaust gas of the internal combustion engine. The exhaust-gas sensor indicates the air ratio lambda and preferably has a two-level characteristic. The sensor output signals are acted upon by a follow-on controller which is preferably a PI-controller. The controller output quantity acts upon the mixture composition in a corrective fashion. In this arrangement, the control oscillation of the controller output quantity is adjusted to a predetermined amplitude by means of a superposed control. In particular, the integral component of the control oscillation is influenced in a manner causing it to have the same amplitude as the proportional component while in the steady operating condition. Thus, it is possible to maintain the maximum control frequency in any operating range of the internal combustion engine so that the controller always operates at its optimum. In addition, the effects of deviations occurring from one engine to another or from one exhaust-gas sensor to another as well as of long-term variations are suppressed.

Title: Brush for cleaning removable dental prostheses
Inventor: SCHMITT WILLI MARTIN
IPC: A46B5/02
Filed: 1984-03-19
Abstract: Conventional brushes which have a rectangular brush base provided with a bristle field and a handle extending from the base are unsuitable for prevention of tartar deposits on the interdental spaces of artificial teeth. In particular, however, adequate cleaning of complicated dental prosthesis holding devices is impossible. In order to achieve a satisfactory cleaning result on all parts of the dental prosthesis the handle part (3) extends, according to the invention, in the shape of an arch over the brush base (2). Furthermore, the bristle zone (1) of the slightly curved brush base (2) is subdivided into three zones, the middle zone (14) of which mainly ensures satisfactory contact on the interdental spaces of the artificial teeth whereas a zone (15) on the end is narrow and located in the longitudinal direction in order to clean, in particular, complicated holding devices. Finally, the other zone (16) on the end has a round cross-section in order to facilitate satisfactory, cleaning engagement in secondary telescopic crowns. The brush according to the invention achieves a satisfactory cleaning result in all regions of the artificial dental prosthesis (Fig. 1). <IMAGE>

Title: Process for the production of anhydrous or largely anhydrous formic acid
Inventor: PRAUN FERDINAND VON DR
IPC: C07C51/48
Filed: 1984-08-01
Abstract: For the production of anhydrous or largely anhydrous formic acid, water and methyl formate are employed in the hydrolysis of the methyl formate in molar amounts from 1:1 to 30:1, the unreacted methyl formate and the methanol formed are removed by distillation and a methyl formate part stream is recycled into the first distillation step above the position of addition of the hydrolysis mixture. The aqueous formic acid is extracted with at least the stoichiometric amount of a relatively high-boiling amine which forms poorly soluble hydroformates with pKa values from 4 to 9 in water, and the amine extract obtained is dehydrated in a distillation column at temperatures from 30 to 120 DEG C, a hydrophobic solvent being employed in the extraction and/or in the dehydration. The dehydrated extract is cleaved into formic acid and amine in a cleavage column at temperatures from 110 to 240 DEG C, formic acid and solvent being obtained as the head product, which is then separated. The methanol, methyl formate, water, amine and solvent obtained are recycled.

Patent DE-3437208-A1 (DE)
Title: Arrangement for generating an improved video signal
IPC: H04N5/228
Filed: 1984-10-10
Abstract: The picture flickering of a video camera which is offered periodically interrupted light from the object to be recorded, is largely eliminated by the fact that the read out of the charge pattern of the video camera is suppressed during the times of existing offer of light and a camera-internal basic illumination used for adjusting the operating point of the image transducer is suppressed during the times when the offer of light coming from the object to be recorded is not present. This results in equal and uniform conditions for building up the charge pattern for all pixels in spite of the interruptions of the offer of light from the object to be recorded.
Patent DE-3500294-A1 (DE)
Title: Component for conditioning air
Inventor: TRAEBING ERNST DIPL ING
IPC: F24F5/00
Filed: 1985-01-07
Abstract: In order to reduce the consumption of heat used in ventilation, the ventilation requirement is to be reduced by conditioning air in an energy-saving manner. In this case, the temperature gradient and the gas pressure gradient between the inside and the outside are to be used to reduce the user-induced load on the air and the risk of damage to buildings and living accommodation. The measures serve in particular to moisten the air and to reduce its CO2 content. The figure shows an exemplary embodiment in which the component (1) is built into an opening of the outside component (12). A temperature gradient between the inside (10) and the outside (11) is produced in the component (1). The air moisture and the CO2 are diffused through the fabric of the surface decoration (30) and the heat-insulating diffusion layer (13) until they reach the condensation surface of the condensor (20). The moisture condenses there, is absorbed by the material of the condensor (20) which produces suction by capillary action and evaporates into the outside air in the condensate evaporator (26) on the outside of the condensor (20). The evaporation process is facilitated by solar radiation. The CO2 gas of the inside air is diffused into the outside air through the larger pores of the condensor. <IMAGE>

The cock plug 8 turns a cam plate 9 which bears, on the upper side, four cams 10a for actuating a changeover switch S4 and, on the underside, two cams for actuating a changeover switch S3. The changeover switches are part of an electronic switch-on and final switch-off means for the stepwise turning of the cock plug. In conjunction with timers and pulse counters, the electronics permit showerings of, for example, 40 seconds to be called up, by means of push buttons, individually and following pauses and, having reached a programmed number of individual showerings, permit the power supply to be switched off. <IMAGE>
Patent DE-3504824-A1 (DE)
Title: Endoscope
Inventor: SCHOELLY WERNER
IPC: F16G13/16
Filed: 1985-02-13
Abstract: An endoscope (1) (Fig. 1) has a control element (2) which is provided with an eyepiece (3) and to which a probe element (4) can be connected. It is possible to provide in the course of the probe element (4) one or more sections, which can be bent, having jointed sections (7). The jointed sections (7) have joint members (11) which are connected to one another via hinge-like swivel joints (12). The jointed sections (7) can be swivelled by means of Bowden wires (8) which act in each case on the end member of a jointed section that is to be adjusted, in the case of mounting points (10). The swivel joints (12) that are provided enable an exact transfer of position, since undesired rotations or twists as well as changes in length in the region of the jointed sections are avoided. In addition, the clear internal cross-section is free to accommodate endoscope built-in components, with the result that it is also possible to realise endoscopes having a very small probe diameter. <IMAGE>
